Quite simply, on any modern computer using floating point
arithmetic it is not true that 3.14 is exactly 3+1/10+4/100.
Floating point arithmetic as implemented in modern computers
simply does not work that way and has not on any mainstream
machine made in the past 10 years or so. And this is totally
independent of Mathematica.
